MRI scans could reveal how smart we really are

The IQ test has long been dismissed as an inaccurate way to discern how intelligent a person really is – but now scientists may have found a better way.
Researchers from Canada’s Western University in Ontario say MRI scans can measure human intelligence – and define what it is.
They discovered that far from being down to one single factor, what is commonly regarded as intelligence is influenced by three different elements – short-term memory, reasoning, and verbal ability. They also found the more variable a brain is, and the more its different parts frequently connect with each other, the higher a person’s IQ and creativity are.
This could lead to radical leaps in AI with machines programmed to think in the same way we do. This study may also have implications for a deeper understanding of another largely misunderstood field: mental health.
